GAN-HEADING MACHINE.

Specification of Letters Patent.

Application med June 7, 1911. serial No. 631,752.

To aZZ whom t may concern:

Be it knownthat I, JULiUs BRENZINGER, a citizen of the United States, residing at Mount Vernon, in the county of Testchester and State of New York, havedinvented certain new and usefulK Improvements in Can- Heading Machines, of which the .following 1s a specification.

.known as tin cans, by what is known as the v double seaming. process.

In a co-pendng application, filed July 5, 1910, Serial No. 570,343, I have shownand described a machine in which the can partsl to b e joined together were held in a statlonary condltion, the seaming operation being performed by seaming rollers which revolve around the can-parts to be joined and their supporting means at a high-velocity.

AsA stated in the application aforesaid, in double-seeming cans which have been filled with foodstuffs, which are generally sealed when the contents thereof are in a heated condition, it is considered desirable to perform the double-seaming operation by revolving theseaming rollers about the can and its supporting means, the latter being retained` in a stationary condition in order that small portions of the ho-t contents of the can will not be thrown off by centrifugal forces before the sealingoperation is completed. Nevertheless, machines of this character are necessarily more complicated and, particularly in the absence of automatic feeding and ejecting devices, vslower in operation, than machines in which the can-parts are rotated by the chuck and the can-supporting platform' and the seaming rollers merely brought into coperation relative thereto.

' This inventionhasgfor its principal object the adaptation of the features of construction and operation of the machine lshown and 4described in my co-pending apframe provided with the usual basev 7. In.

the top of this frame is suitably journaled the main driving shaft 8 which carries the usual fast and loose pulleys'9 and' l() to which power is transmitted in the vusual manner from any suitable source. At the end of the shaft 8 isprovided the bevel gear 11, meshing with the bevel gear'12 on the vertical shaft 13 which is suitably journaled in the arms 14 and 15 projecting forwardly from the frame.

l In the lower portion of the frame 6 is suitably journaled the" shaft 16 driven from the shaft 8 by means of the belt 17 connecting the pulleys 18 and 19 and carrying at its fo-rward end the bevel gear 20. Supported and having bearings in the sleeve or socket 61 on the base ofthe frame, and in the sleeve 62 which has slide bearings in the heads 63 and 64: at the end of the arms 24 and 23, respectively, is the'vertical shaft 22. Loo'sely mounted on said shaft 22 and rotatively supported on the top=.of"t he sleeve or socket 61, is the bevel gear 21 in mesh with the gear 20 on the shaft 16. The gear 21 includes a disk 65, which is provided with a plurality of upwardly projecting pins 66 66 which enter suitable apertures in a disk i or drum 67 fixed uponthe shaft 22. It will be apparent that this constructionand arrangement provides for the vertical reciprocation of the shaft 22 independent of rotatio-n thereof through the intermeshed ,gears 20 and 21. These gears and the pulleys collar 68,the L:ppc-r face of which provides a smooth fiat surface upon which rests the dislr' or platform '26*- This platfornr26 1s lbrovd'ed'witha central pin or pivot which projects into a suitable longitudinal bore in the upper end of the shaft 22, whereby said platform is held in place durih'gprotatio'n" 'of 'the shaft `22. l/l/vhe'nl the constantly rotating shaft 22 is in its fmost depressed or lowermost position, as it is designed Vto be when a can to be seamed 1s being` positioned on the platform 26, said platform may be held against rotation in any-desired manner-ffor instance, as fully shown and described in my coi-pending ap plication, filed February 15, 1903, Serial No. 416,001. As this platform is frictionally rotated, it will be apparent that as the shaft22 is raised a little time will be required to overcome the inertia of said ,plat-- form and thev filled can thereon, whereby rotation thereofl will be startedgradually instead of abruptly. v

rlhe sleeve 62 is vertically reciprocated by means of an accessible and preferably yoke-v shaped hand lever 27,..fulcrumed at128 to the-head 64, the arms 70 of'which are provided with slots into which project pins 71 on Asaid sleeve 62 (a common and well,- known construction) whereby, upon der pression of the handle of the lever 27, the upper end of said sleeve will engage the 'collar 72 fixed on the shaft 22 and raise said shaft with the platform 26 at the upper end thereof. l At the lower end of the shaft 13 is mounted the chuck 25 which, as is well known, is adapted to-enter a correspondingly shaped depression in the can-top or cover and support the latter against the forces of the seaming operation. lVhen a can to be headedv has been placed upon the platform 26, and the shaft 22 raised in the manner described, it will be seen that the can parts will be rapidly rotated at a constant velocity with the can-top firmly held in properposition for the seaming operation.

Fulcrumed at-36 te the frame of the machinecis a lever 37, adapted to be oscillated by the lever 27, the end of one of the arms of the latter being provided with a pin 73 projecting into a slot` 74 in the contiguous arm of the lever 37. To the other arm of said lever 37 is pivoted, the connecting rod 38similarly` pivoted to the end of the lever 39-which is'fulcrumedmt 40 to the frame of the machine. The other end of the lever 39 is provided with a roller 41 which, in what may be termed its normal position, lies' in a seat or pocket 42 in the upper face 'of, a' disk 35 which is 'fixed upon a sleeve 29 through the collar 34, thus checking rotationof said sleeve. From the operating end niemeer :ofthe lever 39iprojectsdownwardly the arm 43 which is provided with the pin 44 at the end thereoffengagedby the end-.of the bellv rcrank lever 45.-y The other-arm ofthis bellcrank lever is adapted, through theusual and well-known connections, to reciprocate the pulley 46 which is loose upon the shaft '33'. lThis pulley 46 is pro-vided with a'fricVJ Athe pulley 46 against the friction disk 59 with sufficient force to make the -'clutch effective and drive the shaft 33.

Thesleeve 29 is mounted on the .shaft 13 to rotate independently thereof, and on this sleeve is mounted the gear 31- in mesh with the worm 32at the end of the shaft 33, whereby said sleeve isrotatcd on thefrotating shaft 13 inanopposite direction (although. this is immaterial) at a very yslow velocity. It 'will be seen, therefore, that when Ithe -lever 27 is depressed, in addition to raising the platform 26 to clampfthe can parts between said platform andthe chuck 25, the connecting rod38 willpbe de pressed, operatingthrough the lever 39 to raise the roller 41 out of the seat or pocket 42 and thus permit rotation of thecam-disk 35 and therewith the sleeve 29. At the same time the arm 43 is de Dressed lowerincthe v r 1 pin 44 and permitting movement of tne bell-crank lever 45 under action of the spring 51' to. make' the friction clutch effec-x tive and rotate the sleeve29 through the .worm 32 and the gear 31.

The sleeve 29 .terminates atpits lower end in a circular eccentric head 30, and mounted in the forward end of thearm 15 is the fixed sleeve which terminates at its lower end in an inverted cup shaped portion which has a flange or rim This flange ory rim formsa support for the seaming-rollercarrying member 54, which has a cylindrical.

mener? ment is controlled and directed by rotation of the eccentric head 30, and the movement is further limited by a pin 55 in the member 54 projecting into a radiallyy directed `'slot 56 in the fiangeor rim 58. The rollercarrying member 54, therefore, is thus held by the pin 55 against rotation but,l under laction f the rotating eccentric head 30,

will be given movement which is the `resultant of reciprocation in the general direction of the slot 56 and oscillation thereof about the pin 55 as a variable center.

The axles of the seaming rollers 57, 58v

p the employment of three rollers is preferinvention.

able. While l have shown in the drawings a; machine in' which three seaming rollers are employed, it is to be understood that a machine having two rollers only or more than three rollers is within the scope of my These rollers' are of the usual construction and configuration and are provided with the usual peripheral grooves in their working edges, adapted to cooperate with the working edge of the chuck 25 in the usual manner to perform the `seam-,

ing operation. lt will be noted that all of these rollers are located on the same side of the member 54, relative to vthe shaft 13, and are in comparatively close proximity to each other.

It will be apparent that under normal conditions (as shown in Fig. l) the chuck 25 is rotating at a substantially uniform velocity `with the seaming rollers 57 and 58 held out of 4coperative relation to the working edge of said chuck. The friction disk 47 being normally separated from the friction face of the pulley 46, there is no rotation of the shaft 33 and consequently of the gearl. A '.l`herefore, the eccentric head 80 will remain at rest and there will be no movement of the sealning-roller-carrying member 54.

As explained, when the assembled parts of the can to be headed are placed upon the platform 26 and the lever 27 -is depressed, these can parts willl be raised and rotation will be gradually imparted thereto until the canparts are firmly gripped between the chuck 25 and the platform 26, and are being rapidly rotated with said chuck and platform. Furthermore.` as explained, depression of the lever` 27 operates to vraise the roller 4:1 from its seat 42 in the cam disk 35, thus releasing the sleeve 29 for rotation, while at the same time the lever 45 is released for movement' 'under the action of the spring 5l to bring the friction face ofthe pulley i6 into contact with the friction disk l? and thus impart rotation to the shaft 33 'and the form 32 to slowly rotate the gear 31 and therewith thesleeve 29 and the eccentric head 30..

I have found it bestfor all practical pur-- poses that the eccentric head 30 should rotate once about its axis during fifteen rotations of the chuck 25. Rotation of this eccentric head within the carrier 54, which is held against rotation in the manner described, will subject said carrier to a bodily movement, clearly shown and described in my co-pending application, Serial No.5'70,34l3, aforesaid, which will not only move all of said rollers to and from coperative positional relationship to said chuck, but will insure ,inldependent action of each roller in succession throughout two orthree rotations of said chuck, completing all of the steps of the seaming operation in from seven to 'nine rotations of said chuck, whereby, during from six to eight rotations thereof all of said rollers will have been withdrawn from coperative positional relation thereto, therefore providing a sufficient clearance for a sufficient interval of time to remove a headed can and adjust on the platform 26 the assembled parts of the next succeeding can to be headed.

It is true that in my co-pending applicaconstruction, is revolved much more rapidly than in the construction shown' herein.

However, the Vrelative positions of the partsV at any given instant of time, under the same general conditions, will be the saine whether the roller-carrying` member and the eccentric head are both rotating'at slightly different velocities, or the carrying member is held against rotation and the eccentric head is rotated therein at a velocity which is equal to the difference between the velocities of the carrying member and the eccentric head where both are designed'to rotate.' Therefore, the first operation l roller 60, the second operation roller 57, the third operation or compression roller 58 will be brought successively into engagement with. the can top, which is supported by the chuck 25, in substantially the same manner as that clearly shown and described in my earlier application aforesaid.

ItI will be noted that rotation of the sleeve 29 will iu'imediately follow the@ raising of the roller -ll from its seat #l2 in`4 the disk '.l`herefore, the lever 2T may be released immediately after depression thereof, the rollei 1ct I ti now traveling along the smooth upper surface of said cam-disk 35 and all ot the parts being thus held in operative positions until the rotating disk again brings the seatllf underneath said roller il, whereupon said roller will at once be forced into said seat by action of the spring 50, releasing the fact that with the exception of the operations of placing` the Iassembled parts of the nnseamed can on the platform 2G, depressing the lever 27, and removing the headed can, the operations of the machine herein shown and described are entirely automatic. The bearings of the seamingrollers are definitely and permanently fixed in the carrying member 5l, and this carrying member, having its bearing upon the eccentric head 230, has atall times definitely established positional relations to the chuck 25, thus insuring a uniformity in operations and permit-ting a nicety of adjustment and a consequent higher degree of perfection in results which would be impossible when the seaming rollers are mounted at the extremities of arms the movements of which are controlled by or through their pivots. The chuck 25 being removably securedto the shaft 13, it will be apparent that in oi'der to adjust my machine to cans of various sizes. it is only` necessary to substitute a chuck, rollercarrying head and platform ot' the proper proportions. Furthermore, it will be noted that rotation ot' the sleeve. 29 and its eccentric head 30 are positivelyT checked automatically with the. rollers 5T, 5S and G0 in their relative positions most remote from the chuck 25, whereby the seaming members are always in position to receive. the can parts upon which they are designed to operate. c

'lhe more particular advantages claimed in connection with the present'. invent-ions are, first, its simplicity: second'. "the absence of a greater or less number of intermediate parts to insure movement of a certain chai'- Aactcr in any particular part: third, the elimination of a great deal of lost motion: fourth, thc marked absence of cams and similar means of independently timing the movement of pai'ts: lit'th..the simplilication oi the problem of lubrication. and. sixth, the. positivcncss of the scaming opcratioiiand the ease ol` adjustment of thc scaming parts. with absolute uniformity oll cll'cct throughvont a lonj"r series ol' operations.

.\l.iny nioililications oil minor details ol `my improved can heading machinc will dinibtlcss readily suggest` themselves to those slullcd .in the art. to which it uppertaiiis,

and I therefore do not limitmy invention to the specific construction herein shown and described.
